Abstract

High steel pipelines will generate remanence during work, transportation, inspection, and maintenance. Due to the existence of residual magnetism, high steel pipelines will have magnetic bias during the welding process, resulting in difficulty in pipeline welding, deterioration of welding quality, and even inability to weld the pipeline. In order to eliminate the residual magnetism in the pipeline as much as possible, the X70 steel pipeline is taken as the research object. Based on Maxwell simulation software, the X70 steel pipeline magnetization and dynamic permanent magnet demagnetization simulation model of X70 steel pipeline are established, and the X70 steel pipeline is magnetized and demagnetized respectively. Taking the magnetic field strength and demagnetization speed of the X70 steel pipeline dynamic permanent magnet demagnetization simulation model as variables, the demagnetization rate of the X70 steel pipeline under different magnetic field strength and demagnetization speed is obtained. Based on the response surface method optimization, the response surface method prediction model is established, and the simulation data is imported into the response surface method prediction model. The magnetic field intensity and demagnetization speed of the X70 steel pipeline dynamic permanent magnet demagnetization simulation model are optimized. It is concluded that the demagnetization effect of X70 steel pipeline is best when the demagnetization speed is 1.0 m/s and the magnetic field intensity is 200000 A/m, and the demagnetization rate can reach 70.73%. The research results can provide a theoretical basis for the permanent magnet demagnetization method of X70 steel pipeline.
